problem description

want Amap"s js api to get the latitude and longitude of the four corners of the current visual area

the environmental background of the problems and what methods you have tried

at present, we have not found this method. We can find a limited map area to get the latitude and longitude of the four corners of the visual area, but how to get the latitude and longitude of the four corners of the visual area without limiting the area

related codes

/ / Please paste the code text below (do not replace the code with pictures)
the method to get the restricted area
defined area map.setLimitBounds (map.getBounds ())
then get the latitude and longitude of the four corners: var limitBounds = map.getLimitBounds ();
limitBounds contains the longitude and latitude of the four corners
is there any other method

what result do you expect? What is the error message actually seen?
